| Catheter-associate urinary tract infections (CAUTI) are urinary system that the patientswith indwelling catheter or48hours after catheter removing, are infected. Retention ofcatheterization is a common operation technique, it is not only the clinical needing, but alsothe main measure of treatment for some certain diseases, the most important complication isthe CAUTI. During the catheter exist, and the CAUTI is also the most common healthcare-associated infections in the global scope. CAUTI affects the reasons that the patienttreatment successful rate, as well as cause the patient stay hospital long, the cost increase.The main clinical control measures of CAUTI morbidity are strengthening the asepticoperation, using sterile equipment antibiotics and so on. The incidence of CAUTI decreasedsignificantly, but it cannot from go up at all infections. Therefore, controlling various riskfactors of CAUTI incidence, recommending CAUTI prevention nursing measures, canreduce the incidence of urinary tract infection of patients, treatment success rate andimproving the quality of life.Objective：The surveys were focused on the patients during catheterization or retention ofcatheterization risk factors of CAUTI, and to suggest the corresponding preventive nursingmeasures, in order to reduce the occurrence of CAUTI and provide a scientific basis.Methods：The Point Prevalence Surveys were carried out in the patients with Catheterization orretention of catheterization in neurosurgery of Changchun City Hospital. The surveyscollected all the hospitalized patients’ information with Catheterization or retention ofcatheterization in neurosurgery on January1,2011. The method of combination of all thepatients in the investigation were investigated and analyzed in neurosurgery. Inclusioncriteria: the patients have a catheterization or retention of catheterization. The investigationcontent included the patient’s sex, age, current diagnosis, past medical history, laboratoryexamination (blood, urine, urine culture, clinical symptoms), the use of antibacterial drugs,underlying diseases and so on. The patients that meet the inclusion criteria in this study were randomly divided intotwo groups. The occurrence of CAUTI patients were the case group, and the other patientswere a control group. The data used Excel database, and SPSS17.0statistics software, thegroup was compared using the chi-square test, P＜0.05for the difference was statisticallysignificant. Considering that some risk factors may be present between interaction, there willbe significant and the possible factors related to incorporate Logistic multi-elementregression analysis, to identify high risk factors associated with CAUTI.Results：1. The patients in this survey of Changchun City in neurosurgery were189,68in themduring hospitalization were catheterization or retention of catheter. The use of urinarycatheter rate was46.03%.2. The average hospitalization days of Catheter associated urinary tract infection groupwere (13.35±4.28).It is significantly higher than the average hospitalization days of thenon-infection group(5.62±3.93). The days of indwelling catheter [1,3),[3,7),[7,14), catheterassociated urinary tract infection incidence rates were9.1%,16.67%,37.5%,64.71%. The ageof catheterization and retention of catheterization patients were <30,[30,40),[40,50),[50,60),≥60years old, and the catheter associated urinary tract infection incidence rates were12.5%,20%,30.77%,33.33%,47.37%. The days of patients use of antimicrobial drugs [1,3),[3,5),≥5days, and the catheter associated urinary tract infection incidence rates were13.64%,15.38%,57.17%. The three top of neurosurgical disease types were cerebralhemorrhage, traumatic brain injury, intracranial tumor, and the catheter associated urinarytract infection incidence rates were36.36%,28.57%,30%.3. The risk factors of catheter associated urinary tract infection include the patient’s daywith ureter≥7days; replacing urine collection bag’s time (1days or≥7days); BPH;hospitalization days; the use of antibacterial drugs≥5days.Conclusion：1. The patient’s time in the Neurosurgery with indwelling catheter prolonged, and thecatheter associated urinary tract infection rate also increased.2. The best time of the patient’s urine collection bag replacement is2to4days. thepatient daily replacement of urine collection bags or more than7days to replace the urinecollection bag, that will make the indwelling catheter patients the incidence of CAUTI weresignificantly increased.3. The suitable replacement time of Folley’s latex catheter in neurosurgery, is every2 weeks.4. The average time stay in neurosurgery, that the patients in catheter associated urinarytract infection’s group was (13.35±4.28) days. the average time stay in neurosurgery, that thepatients in catheter associated urinary tract disinfection’s group was (5.62±3.93) days. theinfection group’s average time stay in neurosurgery was higher than disinfection’s7.73days.Patients with diabetes mellitus, or Hyperplasia of prostate, will increased the catheterassociated urinary tract infection’s rate.5. The research group suggested that strict implementation of aseptic technique;shortening the duration of indwelling catheter; rational administration of antibiotics; tryingto keep the catheter drainage device closed. At the same time, the research for reducingincidence rate of CAUTI intervention study provided a theoretical basis. |
